PNEUMATIC STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 586,728, dated July 20,1897.

Application filed June 24, 1896. Serial No. 596,719. (No model.)

To ctZZ whom it may concern..-

Be it known that we, EDWARD HUBER and JACOB W. MILLER, citizens of theUnited States, residing at Marion, in the county of Marion and State ofOhio, have invented certain new and useful Improvements in Pneiv maticStraw-Smokers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention has reference to an improved strawstacker used,preferably, in connection with threshing-machines in which the straw iselevated in any approx'ed manner either by a simple blast-fan or by theaid of a blast-fan and additional apparatus, said straw being dischargedthrough pneumatic pipes which extend above the thresher. Moreparticularly, however, the invention refers to a revolubledischarging-head combined with the delivery-pipe and mechanism forrevolving said head into various desired positions for the purpose ofdischarging the strawin many directions in stacking it.

To this end the invention consists in the novel construction,arrangement, and combination of the various parts, all as more fullyhereinafter described, and set forth in the drawings, in which- Figure 1is an end elevation of a threshing machine embodying our improvedstacker. Fig. 2 is an enlarged detached perspective view of thestraw-stacker, showing the peculiar construction of the head. Fig. 3 isa cross-section on line m at, Fig. at, illustrating the rotating devicesfor moving the head in various positions; and Fig. i is a verticalsection taken on line 3 7 Fig. 3, further illustrating the actuatingdevices.

In the letters of reference, A represents a threshing-machine of anyapproved type, at the rear end of which is located the usualdischarger-casing B, terminating at the top in the neck 0. The casing isprovided upon its interior with any suitable means for discharging thestraw, such as a blast-fan, operated by means of the belted drive-pulleyD, as plainly illustrated in Fig. 1.

Upon the neck 0, secured to the same in such manner as to admit ofrotation, is the delivery-pipe E. This pipe in turn is provided at itsfree end with a semicircular deflector-casing F, terminating in a hoodG, ca

pable of properly controlling and directing the discharge of the straw.This hood and easing, together with the connection with thedelivery-pipe, constitute the revoluble dis charging-head.

Upon the free end of the delivery-pipe is arranged the circular flangeH. I is a similar flange arranged a short distance below the flange H,and .T is a ring or collar secured between the two flanges and adaptedto be rotated by suitable actuating devices, the flange I acting as theprincipal bearing for said collar. Stationarily secured to the collar Jis the deflector casing F, before referred to, adapted to rotate withthe collar and provided at its end with a series of overlapping segments K, the lower segment being secured to the casin g and the seriesforming the hood or cap in which the casing terminates. The head of thestacker thus formed is capable of any desired amount of rotation,thereby enabling the operator to change the direction of the delivery ofthe straw at will and wit-l1 but little trouble.

The actuating means i" or rotating the head consist of the followinginstrumentalities:

L is a slotted arm one end of which is fixedly secured to thedelivery-pipe E below the collar J, the free end of which extendsupwardly and opposite said collar. Vithin the slotted arm thus describedare pivotally secured, one above the other, two sheaves M and N,preferably for rope and cord. Some distance below the arm and inalinement with the same is secured a similar sheave O.

P and Q are apertured lugs secured, re-" spectively, to the casing andcollar J, preferably diametrically opposite.

R is a cord fixedly secured at one end to the lug P. This cord isadapted to pass from the lug once around the casing and collar, pass ing freely through the apertured lug Q, which acts as a support for thesame, then over the lower sheave N to the sheave O, returning from thelatter over the upper sheave M. Passing then from said sheave it iswound a second time around the casing and collar, passing loosely, asbefore, through the lug Q, and is returned and fixedlyseeured to the lugP. By this construction of actuating mechanism the operator is enabledby pulling on either side of the cord R as it passes over the sheave Oto rotate the head of the stacker into the position desired.

As it is obvious that other actuating devices may be employed than thetype illustrated in the drawings without departing from the spirit ofour invention we do not limit ourselves to the specific constructionshown, although we consider it the preferable type.

In order that the parts maybe operated free- 1 y and undue frictionavoided, the slotted arm is bent or twisted ata point midway between thetwo sheaves, allowing the rope to pass over the middle of each of thesaid sheaves; also, the apertured lug Q, is adapted to extend outwardlysome distance from the collar to form a stop for the revoluble head,thereby preventing the ropes from being cha'fed or cut by the negligenceof the operator in turning the head too far.

It will be seen that by thus constructing ourimproved stacker the usualdeflector-pipe is dispensed with, and in the place of the same isprovided a revoluble head which is capable of being revolved into suchposition as may be desired to discharge the straw properly.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. In a straw-stacker of the kind described, the combination with thedischarging-casing, of a delivery-pipe connected therewith, a headconsisting of a deflector-casing and a hood and revolubly mounted on thefree end of the delivery-pipe, said deflector-casing being open alongone of its sides and said hood being over the open end of saiddeflector-casing and itself open in line with the open side of saiddeflector-casing, sheaves mounted on said delivery-pipe near saiddeflector-casing, and a continuous cord connected to saiddeflector-casing, with one branch running in one direction on thedeflector-casing and over one sheave, and the other branch running inthe other direction on the deflector-casin g and over the other sheave,and thence both branches running to near the rear end of saiddelivery-pipe.

2. In a straw-stacker of the kind described, the combination with adelivery-pipe, of a head consisting of a defiectorca'sing and a hoodrevolubly mounted on the free end of said delivery-pipe, saiddefiector-casingbeing open along one of its sides, and saidhood beingover the open end of said deflector-casing and itself open in line withthe open side of the deflector-casing so as to discharge in line withsaid open side.

3.; In a straw-stackerof the kind described, the combination with thedischarger-casing, of a delivery-pipe connected therewith, a revolublehead arranged upon the free end of the delivery-pipe, a standard securedto the pipe in proximity to the head, comprising a slotted arm, sheavespivotally secured within said arm, and a sheave below the same, anextension or lug upon the revoluble head, and a continuous cord adaptedto engage the lug and sheaves, substantially as and for the purpose setforth.

4. In a straw-stacker of the kind described, the combination with thedischarger-casing, of a delivery-pipe connected therewith, a revolublehead arranged upon the free end of the delivery-pipe, a slotted armsecured to said pipe, said arm being twisted as and for the purposedescribed, sheaves pivotally secured within the arm, and a sheave belowthe same, a lug upon the revoluble head, and a continuous cord adaptedto engage the lug and sheaves, substantially as and in the manner setforth.

In testimony whereof we affix our signatures in presence of twowitnesses.
